Urgent: White particles in tank

I made a change today and removed nitrogen and phosphorus pads from my filter as well as a 15% WC. Though the tank has been up for 11 months, I had a mass die off last week and the tank lost its cycle. The ammonia spiked on monday and the water is testing at 0/0/negligible for ammonia, nitrates and nitrite.

Within the last two hours I've noted a fine white dust inside my tank and the only remaining fish, a lampeyed killie died very suddenly, struggling to get its head above water.

I'm at wit's end here. This tank had been running well, with virtually no fatalities until last week. Could it be my tap water? Here is a picture:

I don't think its the tap water. I'm using the same water as are a few others.

Yeah, I've used the same water, conditioned with stress coat and zyme since I've had this tank.

...fine white dust...
This could have come from a few sources.
1) Chemical reaction among some things in the tank. One example: Phosphate fertilizers should not be dosed with Iron fertilizers. They make a white precipitate.
2) Something added to the tank. Two ideas: Seachem Equilibrium is hard to dissolve, and I sometimes get tired of making it dissolve before adding, so I just dump it (dry) into the filter. Then some bits end up in the tank, eventually dissolving. Other idea: Kids dump things in tanks.
3) Something used in the house that accidentally ends up in the tank. Having any home repairs done? Sheetrock dust and other things can find their way into the water.

I am not sure if the past week's history shows anything that it could be.

It's this:

I just dosed both Phosphorous and Iron, along with trace, nitrogen and potassium. I had never had a reaction before, probably thanks to the pad that leeched Phosphate out of the water.

I'm not sure why it killed the fish though, but at least now I know what this thing is.

Thank you very, very much. I am grateful.

I had my sons tank recycle for no apparent reason about 3 weeks ago. The only thing I could think of to cause this was the API Quik Start that I started useing when I did WCs. The guy at the lfs said that he has seen tanks die then recycle using similar products. He thinks that if you add to much you starve the BB and have a die off of the BB basically recycling the tank. Wick at tht time we add more to help the tank a n cause the tank to recycle again and stress out the fish

I don't know where I'm going but I'm on my way.

I'm starting to learn that the less you do with a cycling tank, the better. :/

That is true. Set it up the best you can, then just check to be sure it stays that way.
